To all 11:71 om it 'muy 2o/1.667%.-

Be it known that l, Gnonen W. WHITE, a citizen of the United States, resldingat Waco, in the county of McLennan and State of 5 Terras, have invented ctutain new and useful Improvements in FluidfBurner Fire-Logs; and I do hereby declare the 'following to be a full, clear, and exact description ot the invention, such as will enable others skilled in Io the art to which it appertains to 'make and use thc same.

My invention relates to llnid-linlrner iire- I logs adapted to be placed in ure-chambers of furnaces, stoves, boilers, brick kilns, tire- 15 places and gratos, or in any other ,lire-ehanr ber, for warming buildings, generating steam, burning brick, cooking, and smelting ores and products thereof 5 and it consists in the novel construction of portable fluid-burner fire-logs, as hereinafter described and specifically claimed. In the accompanying drawings, Figure l is a vertical longitudinalsection ot' myimproved fluid-burner tire-log with the duid-supply and the air-induction connections thereof. Fig. 2 is a vertical transverse section of the saine, looking toward the supply and the air-induction connections. Fig. 3 is a vertical longitut'linal section of my tirelog applied to a locomotive-boiler. Fig. i is a horizontal section of a brick-kiln with my invention ap plied to it at two ends; and Fig. 5 is a longitudinal section on a reduced scale, showing a modification of the invention, I A. in the drawings represents the tubular body of. the duid-burner rire-log, which in cross-section may be in the forni ot' a circle, ellipse, ovate, polygon, or any other suitable geometrical figure. This body is constructed Wit-li open ends and with burner or jet perforations a in its periphery along nearly its entire length and partly around or nearly over its circumference, as circumstances or the use ot' the log may require.

The open-ended body porl tion A is closed at its ends by strong asbestus-packed iianged metallic heads A A2, the Q flanges a a of which overlapping and encircling the ends of the said body and the edges of the asbestus packing-sheets AZ", as shown.

Through each of the heads a perforated tube, B, for conduction and distribution of the fluid fuel, is inserted, and on the ends of this tube screw-threads Z) b are cut', and upon these threaded portions nuts cpc', packed with asbestos, as shown, are applied outside the heads. \l"hile the tube B serves as a distributer and conductor ot' the fluid, it, -with the nuts c c', serves also as a means for tying the heads and body A together. Another perforated tube, C, having screw-threads b2 b3 and packed nuts c2 c3 atv its ends, is passed through the heads A A? and made to serve as a tie between the body A and the heads, same as the tube B, While it also serves the purpose of conducting and distributing air 'for insuring air at the jet-passages of the fluid-burner fire-log. The tube B is perforated, preferably, only on top with one, two, or more rows of jet-passages, d, while the tube C is preferably perforated all round or over its circumference with air-inducting passages f, and the tube B is placed in about the same vertical plane with the tube C, some distance above it, as shown.

lVithin the lire-log structure asbestus, in a comminuted or disintegrated condition, is pla-ced so as to completely ll the jet-passages and chamber formed and inclosed bythe body A and heads A A2, and also surround the fluid-supply tube and air-induction tube, as illustrated at ill in the drawings. The asbestus, while placed quite compact-ly in the. ireleg, forms numerous capillary passages for the regular and proper ilow ot' the fluid through it to the jet-passages, and also for the circulation of air for insuring combustion of the fluid at said jet-passages- The pipe B is connected with a supply-pipe from the Huid-supply reservoir by means ot' a coupled vertical pipe, B', as shown, and the air coiiducting and distriubtingpipc O is connected with a vertical coupled ai r-supply pipe, C', as shown, and the vertical pipes B C are provided, respectively, with a cu 1:-oi" and regulation cock, as indicated at '52 C2.

At the upper end of the air-supply pipe C a funnel-shaped monili-piece, C3, is provided, and this may be fitted seas to be turned to the wind as occasion may require. ln the drawings by 4 I have shown the manner in which a series of uuid-burner fire-logs may be applied in the eyes of an ordinary brick kiln, as D, and the series connected by a IOO transverse pipe, B3, adapted for forming communication with the main supply-pipe of the oil-supply reservoir B4 and with a series of vertical coupled pipes similar to that B. In this use of the invention t-he air-supply pipes will all havefa funnel-shaped mouth-piece, as 03 adapted to be turned to the wind, and when so turned strong currents ot` air will be forced down vthe pipes into the fire-log, and the burning of the oil at the jet-passages will be very perfect, and the Haines produced will` be forced with great energy away from 'the j et-passages and whirled in great burning` volumes into the arches and amid the stacks of brick, thus effecting the burning of the brick in a shorter time and in a more uniform manner than heretofore with ordinary ar rangements for burning.

In Fig. 3 of the drawings I have illustrated the manner in which the invention may be applied to the lire-chamber of a locomotiveboiler, E, and on the air induction or supply pipe C" a funnel-shaped mouth-piece, C3, is provided. With this arrangement the air is forced by the motion of the locomotive down vthe pipe into the fire-log, andwhile the combustion at the jet-passages is insured the whirling of the flames produced along the flue or fiues of the boileris accomplished and a greater amount ofv effective heat from a given amount of fuel is secured. In the manufacture of my improved Huidburner fire-logs I may employ either metal. or fire-clay bodies A; but it is preferable to make the body portion A of re-clay or equivalent argillaceous material, because such material is fire-proof, enduring, and not liable to corrosion, and. in connection with this fire-clay tube it-is preferable to employ strong `cast-iron heads with binding end flanges and asbestus or other fire-proof protection-packing at the joints between the body and the head and where the nuts are applied on the pipes, so as to make the joints oil-tight, and in order to thus use a clay tube or cylinder and cast metal heads means for binding the same together must be provided, and such means are very conveniently and economically secured by myl1ereinbefore-described mode of extending the perforated pipes B and C through and beyond the heads A A2, threading said extended ends, and applying' nuts thereon for binding the heads and body together, and at the same time securing the pipes in their proper positions. By `having the heads removable,whether the body portion is made of clay or metal, the filling' of asbestus or other equivalent fire-proof material can be conveniently introduced into the chamber of the firelog, and by employing two fire-proofs materials in the construction of the fire-log-to wit,

nre-clay and asbestu s-great savingis effected, for there will be very little expense after a stove, grate, furnace, locomotive, or kiln has once been equipped with such logs, While a further greater sayin g will be effected in cost for fuel. consumed, as coaloil or petroleum employed in connection with my logs is found very effective and economical for the various uses mentioned and far preferable to other fuels, the smoke being consumed and sparks and cinders avoided. I prefer making the logs for ,fire-places, stoves, and grates with flattened bottoms, as they maintain their position better when of that form than when round; but theform is immaterial. The logs may be perforated all round when set above the bottom of the furnace or kiln. Vhen the logs are small and used for stoves and grates, the air-pipes may be left off; but this would not be a departure from the principle of my invention, as the fire-log formed of a tubular body portion, preferably of {ire-clay, metal heads, perforated oil and tie tubes, andthe asbestus filling constitutes one leading fea ture, and the addition thereto ofv the air 'find-uction and distribu'ting'tube another important feature of invention.

My portable fire-log is adapted for application to locomotives, brick-kiln, and other furnace chambers, and can be removed. for repair or other purpose without disturbing the firebox and other 'parts of such structure. Icontemplate as a modification of my invention to cut off the inner extension of the oil-supply tube and to close the opening in the head through which the end of said extension passes, and to fill the space which said eXtension, if used, would occupy with asbestus, as illustrated in Fig. 5. Vith this construction the comminuted asbestus alone would be the means for conducting the oil to the j et-burn er passages. I, however, prefer to employ the perforated tie-tube for conducting and distributing the oil, as the same is much the best mode.

It will be understood from the foregoing description and accompanying dra-wings that it is essential that the body portion of 'my fluid-burner fire-log shall. be made of strong rigid material-such as iire-clay or heavy cast or wrought metal-and that the heads shall be of strong rigid material-such as cast or wrought metal-iu order that the iirelog may be enduring and capable of withstanding the IOO IIO

great and continuous heat of fires such as are required for running brick-kilns, locomotive, and boiler furnaces; also to be adapted for constant use as a substitute for fuel-such as coal and wood-iu stoves, heaters, and fireplaces.

It will further be secu that the perforated oil-distributing tube or air-distributing tube, or bot-h tubes, require to have strong screwthreads cut upon their ends; that such ends shall extend both outside the heads and have strong nuts applied thereon, so that the heads and body portion of the log can be bound strongly together, which binding of the said parts is enhanced by providing strong over lapping fianges on the heads. It will be further seen that there is a vgreat advantage in the saving of expense, as well asfiitility, in

providing for both distributing the oil andsupplying', distributing, and forcing the air by means of perforated tubes, which also serve as tietubes between the heads and the body of the fire-log.

It will further be seen that it is very important to surround both the oil-distributing and the airdistributing tubes With coinminuted asbestus and to pack the joints with sheets of the same material, as this substance is fireproof and affords every facility for the circu lation of the air and iiuid or oil.

My invention in the construction and form of its parts, the proportions or thickness and strength thereof, and the purposes and uses for Which it is designed Would be of no practical use as a re-kindler; nor would iirekindlers nor vapor-burners, dec., constructed as in Letters Patent Nos. 373,465, 196,613, 31,466, 135,011, and 252,014 be capable of practically and usefully serving the purposes for which my invention is intended.

VWhat I claim as new, and desire to secure by Letters Patent, is#

l A portable duid-burner fire-log having, in combination, a perforated tubular body, metallic removable heads, a fluid-su pplyin g tube, u perforated air-induction distributing tietube provided with screw threads and nuts on its ends outside the heads, and a eomminuted or disintegrated fire-proof filling surrounding the perforated portion of the airtube and oc copying the chamber of the body, substantially as and for the purpose described.
